From f25b03a7bd260b939b1a6aa69ca518d9848bb63a Mon Sep 17 00:00:00 2001 From: Sathya Perla Date: Sun, 30 May 2010 23:34:14 +0000 Subject: be2net: replace udelay() with schedule_timeout() in mbox polling As mbox polling is done only in process context, it is better to use schedule_timeout() instead of udelay().
